Renaissance humanism is the study of classical antiquity, at first in Italy and then spreading across Western Europe in the 14th, 15th, and 16th centuries. The term Renaissance humanism is contemporary to that period — Renaissance (rinascimento "rebirth") and "humanist" (whence modern humanism; also Renaissance humanism to distinguish it from later developments grouped as humanism).[1]

Early Italian humanism, which in many respects continued the grammatical and rhetorical traditions of the Middle Ages, not merely provided the old Trivium with a new and more ambitious name (Studia humanitatis), but also increased its actual scope, content and significance in the curriculum of the schools and universities and in its own extensive literary production. The studia humanitatis excluded logic, but they added to the traditional grammar and rhetoric not only history, Greek, and moral philosophy, but also made poetry, once a sequel of grammar and rhetoric, the most important member of the whole group.[3]

Humanism was a pervasive cultural mode and not the program of a small elite, a program to revive the cultural legacy, literary legacy, and moral philosophy of classical antiquity. There were important centres of humanism in Florence, Naples, Rome, Venice, Genoa, Mantua, Ferrara, and Urbino.

In Italy, the humanist educational program won rapid acceptance and, by the mid-15th century, many of the upper classes had received humanist educations, possibly in addition to traditional scholasticist ones. Some of the highest officials of the Catholic Church were humanists with the resources to amass important libraries. Such was CardinalBasilios Bessarion, a convert to the Catholic Church from Greek Orthodoxy, who was considered for the papacy, and was one of the most learned scholars of his time. There were several 15th-century and early 16th-century humanist Popes[4] one of whom, Aeneas Silvius Piccolomini (Pope Pius II), was a prolific author and wrote a treatise on The Education of Boys.[5] These subjects came to be known as the humanities, and the movement which they inspired is shown as humanism.

The Cambridge Dictionary of Philosophy describes the rationalism of ancient writings as having tremendous impact on Renaissance scholars:

Here, one felt no weight of the supernatural pressing on the human mind, demanding homage and allegiance. Humanity—with all its distinct capabilities, talents, worries, problems, possibilities—was the center of interest. It has been said that medieval thinkers philosophised on their knees, but, bolstered by the new studies, they dared to stand up and to rise to full stature.[12]

Inevitably, the rediscovery of classical philosophy and science would eventually challenge traditional religious beliefs. In 1417, for example, Poggio Bracciolini discovered the manuscript of Lucretius, De rerum natura, which had been lost for centuries and which contained an explanation of Epicurean doctrine, though at the time this was not commented on much by Renaissance scholars, who confined themselves to remarks about Lucretius's grammar and syntax.[13]Lorenzo Valla, however, puts a defense of epicureanism in the mouth of one of the interlocutors of one of his dialogues.[14] Valla's defense, or adaptation, of Epicureanism was later taken up in The Epicurean by Erasmus, the "Prince of humanists:"

If people who live agreeably are Epicureans, none are more truly Epicurean than the righteous and godly. And if it is names that bother us, no one better deserves the name of Epicurean than the revered founder and head of the Christian philosophy Christ, for in Greek epikouros means "helper." He alone, when the law of Nature was all but blotted out by sins, when the law of Moses incited to lists rather than cured them, when Satan ruled in the world unchallenged, brought timely aid to perishing humanity. Completely mistaken, therefore, are those who talk in their foolish fashion about Christ's having been sad and gloomy in character and calling upon us to follow a dismal mode of life. On the contrary, he alone shows the most enjoyable life of all and the one most full of true pleasure.[15]

The period from the fourteenth century to the seventeenth worked in favor of the general emancipation of the individual. The city-states of northern Italy had come into contact with the diverse customs of the East, and gradually permitted expression in matters of taste and dress. The writings of Dante, and particularly the doctrines of Petrarch and humanists like Machiavelli, emphasized the virtues of intellectual freedom and individual expression. In the essays of Montaigne the individualistic view of life received perhaps the most persuasive and eloquent statement in the history of literature and philosophy.[16]

With the Counter Reformation initiated by the Council of Trent (1545-1563), positions hardened and a strict Catholic orthodoxy based on Scholastic philosophy was imposed. Some humanists, even moderate Catholics such as Erasmus, risked being declared heretics for their perceived criticism of the church.[19]

The historian of the Renaissance Sir John Hale cautions against too direct a linkage between Renaissance humanism and modern uses of the term humanism: "Renaissance humanism must be kept free from any hint of either "humanitarianism" or "humanism" in its modern sense of rational, non-religious approach to life ... the word "humanism" will mislead ... if it is seen in opposition to a Christianity its students in the main wished to supplement, not contradict, through their patient excavation of the sources of ancient God-inspired wisdom"[20]

^The term la rinascita (rebirth) first appeared, however, in its broad sense in Giorgio Vasari's Vite de' più eccellenti architetti, pittori, et scultori Italiani (The Lives of the Artists, 1550, revised 1568) Panofsky, Erwin. Renaissance and Renascences in Western Art, New York: Harper and Row, 1960. "The term umanista was used in fifteenth-century Italian academic slang to describe a teacher or student of classical literature and the arts associated with it, including that of rhetoric. The English equivalent 'humanist' makes its appearance in the late sixteenth century with a similar meaning. Only in the nineteenth century, however, and probably for the first time in Germany in 1809, is the attribute transformed into a substantive: humanism, standing for devotion to the literature of ancient Greece and Rome, and the humane values that may be derived from them" Nicholas Mann "The Origins of Humanism", Cambridge Companion to Humanism, Jill Kraye, editor [Cambridge University Press, 1996], p. 1–2). The term "Middle Ages" for the preceding period separating classical antiquity from its "rebirth" first appears in Latin in 1469 as media tempestas.

The unashamedly humanistic flavor of classical writings had a tremendous impact on Renaissance scholar.

^Only in 1564 did French commentator Denys Lambin (1519–72) announce in the preface to the work that "he regarded Lucretius's Epicurean ideas as 'fanciful, absurd, and opposed to Christianity". Lambin's preface remained standard until the nineteenth century. (See Jill Kraye's essay, "Philologists and Philosophers" in the Cambridge Companion to Renaissance Humanism [1996], p. 153.) Epicurus's unacceptable doctrine that pleasure was the highest good "ensured the unpopularity of his philosophy" (Kraye [1996] p. 154.)

^Charles Trinkhaus regards Valla's "epicureanism" as a ploy, not seriously meant by Valla, but designed to refute Stoicism, which he regarded together with epicureanism as equally inferior to Christianity.
